FLER bit setting conditions are as follows:
1. When the flash memory of the relevant address area is read during programming/erasing
2. Immediately after exception handling (excluding a reset) during programming/erasing
3. When a SLEEP instruction (including software standby) is executed during
4. When the CPU releases the bus to the DTC
Error protection is released only by a reset and in hardware standby mode.
Figure 21A-14 shows the flash memory state transition diagram.
